ARCH SUIPOBT.

Application filed August 7,1922. Serial No. 58034 3.

To all whom it may concern: I

Be it known that 1, CHARLES L. CnAINn, a citizen of the United States,residing at Meadville, in the county of Crawford and State ofPennsylvania,have invented new and useful Improvements in Arch Supports,of which the following is a specification.

This invention is designed to improve arch supports. Such supports musthave sufficient rigidity or supporting quality to carry the arch. At thesame time they mus conform to the local variations encountered in archesto distribute the support. In accomplishing this I utilize a series ofwire arched members preferably of round, or wire having equal crossdimensions which wires are rigidly connected by welding or otherwisewith the end plates, the rigid connection with the end-platesretainingthe wires in their'arched form and in proper relation to eachother and forming a means to which the pad covering the arched wires maybe permanently secured. It is also desirable to provide such a devicewith means for supporting the metatarsal depression and to have thissupport adjustable to fit difi'erent conditions. Other features of theinvention will appear from the specification and claim.

The invention is illustrated in the accompanying drawings as follows pFig. 1 shows a section of the support on the line 11 in Fig. 2.

Fig. 2 a bottom view of the support.

Fig. 3 a section on the line 3-3 in Fig. 1.

Fig. 4 a. side elevation of the filler forming the local metatarsalsupport. v

Fig. 5 a bottom view of the filler.

1 marks the rear end plate and 2 the front end plate. These areconnected by the wires 3, the ends of which are rigidly secured byelectric welding, or otherwise to theplates 1 and 2. These wires formthe arch a's'clear- 1y shown in Fig. l and are so arranged as to beproperly spaced across the support. The wires are preferably ofapproximately equal cross dimensions ordinarily of round wire so as toreadily flex not only in the direction of the arch but slightly sidewiseif necessary to conform to the shape of the arch of the foot. On theother hand the rigid connection with the plates assures the holding ofthe wire so that it directs its supporting force upwardly, in otherwords, it prevents the Wires turning and thus yielding without givingthe proper support.

The pad 4 conforms to the general shape of the arch and is supported toat least one of the plates by rivets 5. It has the usual side support 6.Efforts have heretofore been made to secure such pads by means ofcements and otherwise but diiliculty has been encountered as to this byreason of the heat, wear and moisture to which the pad is subjected.

The front plate 2 has a transverseslot 7 into which thetongue 8 of thefiller 9 extends. This filler is arranged under the pad 4- and forms alocal arch 10 for the metatarsal depression. The filler may be shiftedcrosswise along the slot 7 so that it may be made to conform to the footof the wearer. This filler may be made of any desirable material such asrubber or aluminum.

The rear plate 1 is provided with an open ing 11 into which the pad'l isdepressed. This forms an oscalsis depression in the pad.

I prefer to provide the pad with openings 12 which being over the openwires 3 and these wires being spaced ordinarily from the bottom of theshoe give ample ventilation to the foot.

.VVhat I claim as new is In an arch support, the combination of endmetallic plates; and a series of co11nect ing resilient wires of archedform extending between the plates and rigidly connected thereto.

In testimony whereof I have hereunto set my hand.

' CHARLES L. CRAINE.
